GradeBeautyLayerSet provides a simple way to specifically grade multiple cg layers using a [LayerSet](core
.md#layersets)
Image processing math is exactly like the Nuke Grade node except that, you can grade multiple layers at the same time
| knob name | type | what it does |
|---|---|---|
| layer_set | enumeration | decides which LayerSet to use |
| output_mode | enumeration | specifies the type of output, add or copy |
| reset values | button | resets all color knobs to their defaults |
| mode name | what it does |
|---|---|
| copy | outputs only the modified layers to the target layer (added together) |
| add | this first subtracts all layers from the target layer, then adds each of them back |
